fullrfk           Scilab Group           Scilab Function            fullrfk
NAME
   fullrfk - full rank factorization of A^k
  
CALLING SEQUENCE
 [Bk,Ck]=fullrfk(A,k)
PARAMETERS
 A          : real or complex matrix
            
 k          : integer
            
 Bk,Ck      : real or complex matrices
            
DESCRIPTION
   This function computes the full rank factorization of A^k i.e. Bk*Ck=A^k
  where Bk is full column rank and Ck full row rank. One has
  range(Bk)=range(A^k) and ker(Ck)=ker(A^k).
  
   For k=1, fullrfk is equivalent to fullrf.
  
EXAMPLE
 A=rand(5,2)*rand(2,5);[Bk,Ck]=fullrfk(A,3);
 norm(Bk*Ck-A^3,1)
SEE ALSO
   fullrf, range
